Sonus addresses evolving MNO security challenges in 4G-LTE networks with a new security architecture, developed with Palo Alto Networks, that provides full visibility and enforcement associated with signaling and multimedia traffic, with a focus on preventing malware.

The security architecture is designed to increase mobile subscriber security, improve customer experience, reduce mobile operator total cost of ownership (TCO) and protect mobile network infrastructure from service abuse and revenue losses.

MNOs can now leverage their Sonus P-CSCF and IBCF deployments to detect and mitigate anomalous IP communications traffic from rogue endpoints, as well as obtain complete visibility and threat prevention capabilities provided by the Palo Alto Networks Next-Generation Security Platform. With this security architecture in place, MNOs can reduce capital costs by limiting the over-provisioning of networks while implementing a more effective overall security posture in conjunction with growing IP Communications services, such as VoLTE and VoWiFi. Additionally, MNOs can deter theft of service and ensure greater network availability and quality of experience for mobile subscribers by preventing targeted network attacks and blocking malware targeting mobile devices.

Quotes:"The Sonus and Palo Alto Networks architecture brings together the unique capabilities offered by each company to deliver a best-in-class security solution for mobile operators that unifies LTE data and VoLTE security policy and enforcement," said Kevin Riley, Sonus CTO and senior vice president, Engineering. "Establishing a secure mobile network for the Internet of Things will be a key differentiator for mobile operators and their customers in the coming years. We are looking forward to working with Palo Alto Networks to continue this momentum as we get ahead of identity and security issues and redefine this evolving landscape together."

"Mobile network operators must have full visibility into all types of mobile network traffic in order to prevent cyberattacks. The joint architecture announced today by Sonus Networks, in collaboration with Palo Alto Networks, provides MNOs with comprehensive traffic visibility within their infrastructure, and combines the cyber breach prevention capabilities of our Next-Generation Security Platform with Sonus' advanced security for the VoLTE/voice network," said Scott Stevens, Palo Alto Networks senior vice president of Global Service Provider Sales. "This joint architecture provides active coordination between our platforms to provide a new level of security into the VoLTE/VoWifi network."
